Prior to 1501, Lo Sparviero was tasked with assassinating one of Florence guards, but while carrying out his mission, he was discovered by other guards. After having cleared a bloody path among them, he had to flee, climbing one of the churches of the city to escape.
Fighting the Crows
In 1501, Lo Sparviero was tasked with eliminating Borgia mercenaries disguised as tax collectors inside the walls of Monteriggioni. The three Borgia mercenaries were successfully assassinated, and the later, the Assasins found out that the mercenaries were a distraction and that one of Mario Auditore's hidden chests underneath Villa Auditore, in the Auditore Family Crypt, had been stolen.
Lo Sparviero was later tasked with assassinating Pietro de Galencia, a Templar doctor in Monteriggioni who was responsible for the stolen chest. Pietro's mission was to find and steal the blueprints of the Hidden Blade, hidden in the Assassins' hideout, and to accomplish his mission, Pietro kidnapped and tortured an old man, father of an Assassin, into telling him the location of the chest. Lo Sparviero managed to assassinate him, however, Pietro had already delivered the chest to the Templars.
In 1506, Lo Sparviero was tasked with protecting Leonardo da Vinci from a group known as "the Crows" after he had been kidnapped by the Hermeticists, led by Ercole Massimo. The Crows were staved off and Leonardo was kept safe by the Assassin.
Some time later, Lo Sparviero found the chest that had been stolen from Monteriggioni years ago. Machiavelli tasked three Assassin apprentices with the mission of recovering the chest, however, the three of them were killed by the Templars. In retaliation, Machiavelli sent Lo Sparviero himself to recover the chest and avenge the fallen Assassins. He succeeded in his mission and brought back the chest, as well as the Hidden Blades of the apprentices. Machiavelli opened the chest, and found a modified version of the Hidden Blade.
After that, Machiavelli received a letter from Demetrio il Silente, a weaponsmith that was forced to create modified versions of the Hidden Blade for the Crows. When the weaponsmith refused to continue creating more weapons for him, Cesare cut his tongue. This caused Demetrio to plot against Cesare, asking Machiavelli for help. Lo Sparviero managed to save Demetrio by bribing the captains of the guard. The Assassin took Demetrio to Machiavelli, where the weaponsmith confirmed that the modified Hidden Blade that they had recovered was a "Corvix Blade", an upgraded version of the Hidden Blade created with the blueprints stolen from Mario's chest.
Machiavelli, after noticing some strange events happening near the Colosseum, sent Lo Sparviero to investigate. He discovered a large amount of boxes full of Corvix blades and that the Crows were responsable.The Assassin then decided to kill the camp's leader, a man called Matteo. Lo Sparviero followed Matteo to the top of the Colosseum, where he killed him.
The Assassins then took over the camp, driving out the Crows and capturing a bald man who was previously seen talking to Matteo by Lo Sparviero. He said his name was Sirus Favero and claimed to be a mere arms merchant working for Cesare, although confessing his hatred towards the Borgias. Machiavelli decided to let to Sirus join them as long as he told them all he knew about Cesare and the Crows.
